Notes

1) Significant regional variations in band utilization and noise sources preclude one plan suitable for all parts of the country. Locally coordinated plans always take precedence over national recommendations.
2) May be used for either repeater inputs or weak-signal as regional needs dictate.
3) Division into channels and/or separation of uses within these segments may be done regionally based on needs and usage, such as for 2 MHz-wide digital TV.
4) These segments may also be designated regionally to accommodate alternative repeater splits.
5) Simplex FM calling frequency 927.500 or regionally selected alternative.
6) Additional FM simplex frequencies may be designated regionally.

Notes

FCC announced that all Amateur Radio use of the band 3.45 - 3.5 GHz must cease effective April 14, 2022. See http://www.arrl.org/3-ghz-band for detailed history.
Note 1 - Includes all other emission modes authorized in the 9 cm band whose necessary bandwidth does not exceed the suggested bandwidths listed.
Note 2 - Weak Signal Terrestrial legacy users are encouraged to move to 3400.3 to 3401.0 MHz as time and resources permit.
Note 3 - Broadband segments may be used for any combination of high-speed data (e.g. 802.11 protocols), Amateur Television and other high-bandwidth activities. Division into channels may be done regionally.
Note 4 - Per ITU RR 5.149 from WRC-07, these band segments are also used for Radio Astronomy. Amateur use should be first coordinated with the National Science Foundation (esm@nsf.gov).
